Answer 1

I had same problem of receiving push messages, even though GCM server replies "Success", because of wifi privacy. When I used my company wifi, I coudn't receive message in mobile, since they were blocked GCM server port . So, even your wifi also could be a one of the reason. check it once { this answer is for others , who may face this}

Answer 2

can you please check in your device did you login in gmail account?

if you are not logged in you will not get push notification.

first login in gmail then then try may be it will work.

确保你在主包中有GCMIntentService.class接收来自GCM服务器的广播（更喜欢与GCM相关的任何东西在主包中）我希望这项工作
